Title: Manufacture of hydrogen peroxide
IPC: C01B15/023
Filed: 1952-11-25
Abstract: In the production of hydrogen peroxide by reduction and auto-oxidation of alkylated anthraquinones and their tetrahydro-derivatives dissolved in a two component solvent mixture consisting of a quinone solvent and a hydroquinone solvent, a diphenyl hydrocarbon, having 12-18 carbon atoms in the molecule and completly saturated except for the two phenyl nuclei, is employed as a constituent of the solvent mixture. Suitable diphenyl hydrocarbons are diphenyl, methyl diphenyl, amyl diphenyl, diphenyl methane, ethane, and propane, methyldibenzyl, ditolyl and ditolyl ethane. Mixtures of diphenyl hydrocarbons or blends with inert organic diluents may be used, and they have molecular weights 154-240, boiling points above 250 DEG C. and vapour pressures 1 mm. Hg. Hydroquinone solvent constituents referred to are a mixture of triphenylphosphate and diphenyloctylphosphate, tetralecanol, and trioctylphosphate. Anthraquinones may be the 2-ethyl-, 2-methyl-, 2-isopropyl-, and 2-tertiary butyl-anthraquinones or the corresponding tetrahydro derivatives.  In the examples the solution of the anthraquinone in the mixed solvent is washed with 50 per cent. aqueous K2CO3 or KOH, and the resulting washed oil, after rejecting the aqueous wash, is passed through activated alumina shaken with 40 per cent. aqueous K2CO3 and filtered. The solution is hydrogenated at 36 DEG C with a porous nickel catalyst in a vessel equipped with an agitator.  The reduced solution is drained through a sintered glass filter, to remove catalyst to another agitator-equipped vessel, wherein it is oxidized at 36 DEG C. in an air atmosphere with continuous replacement of the absorbed oxygen by metered pure oxygen. When oxygen absorption ceased and the solution changed to yellow hydrogen peroxide was extracted by successive water washing.

IPC: B61D29/00
Filed: 1929-10-04
Abstract: 329,603. Lignes. Telegraphiques et Telephoniques. Oct. 18, 1928, [Convention date]. Cables with artificially modified cap p a c i t y; cables, machines and' processes for making. - In order to reduce capacity unbalance with regard to earth in the phantom circuit of a telegraphic etc. cable of the kind having pairs of conductors twisted together, the pitches of twist of the pairs are interchanged at different points of the line by sectioning the conductors and crossing the pairs when rejoining, or by interchanging the pitches of twist by controlling the driving gear in the twisting machine. In the machine shown in Fig. 2, gear wheels 16, 17 are mounted on a shaft 18 slidable in a hollow shaft 19 which is connected to a gear wheel 12. The wheel 12 is driven from the transmission shalt. In the position shown, the wheel 17 engages a gear wheel 21 which transmits the speed of a shaft 20 to the frame 6 of the machine. When the shaft 18 is slid to the upper position, the wheel 16 gears with a wheel 22 on the shaft 20. The machine is symmetrical with reference to the transmission shaft, so that the driving of a second frame 7, through gear wheels 23, 24 is similar. The gears 16, 23 or 17, 24 may be thrown simultaneously in mesh by a lever. In a modified construction shown in Figs. 4, 5, the two different speeds of the frame 6 are obtained by a gear wheel 25 with driving members 26 and a shaft 20 carrying a ratchet wheel 27. When the higher speed of rotation of the shaft 20 is desired, a gear wheel 28 engages a gear wheel 29 on the shaft 20. The gear wheel 25, driven by a gear wheel 30, turns more slowly than the wheel 29 so that the driving members 26 slide over the ratchet wheel 27. To obtain the lower speed the wheel 28 is thrown out of gear and the wheel 25 engaging the wheel 30 drives the shaft 20, the driving members 26 engaging the ratchet wheel 27. The frame 7 is similarly driven, the movement of a lever simultaneously effecting the change over of speeds of both frames 6, 7.

Abstract: 1,096,259. Voltage control of A.C. loads; overcurrent protection. SIEMENS-SCHUCKERTWERKE A.G. July 7, 1966 [July 7, 1965], No. 30648/66. Heading H2H. The A.C. voltage to a rectifier 3 is controlled by varying the quenching instant of antiparallel connected thyristors 4, 8 which are fired preferably at or near the start of each appropriate half cycle of the main A.C. supply U. Each thyristor 4, 8 is quenched by discharge of a capacitor 6, 10 consequent upon firing of controlled rectifiers 5, 9, the quenching of one thyristor causing the control capacitor of the other thyristor to be charged in readiness for quenching action during the next half cycle, Fig. 2 (not shown). Initially one of the capacitors is charged by applying the A.C. supply U with both thyristors non-conductive. The firing instants may be shifted so that they and the quenching instants are symmetrical about the peak value of each half cycle of the A.C. supply. The rectifier 3 may supply an electrostatic precipitator, a radio transmission valve or a welding installation. The quenching instant may be made dependent on voltage fluctuation in the load, e.g. flashover in a precipitator, to protect the load being supplied.

Abstract: 1,174,252. Pressure-reducing valves; fluid pressure brakes. DUNLOP CO. Ltd. 7 July, 1967 [9 July, 1966], No. 30930/66.- Headings F2F and F2V. A pressure-reducing valve for an aircraft braking system has a spool 5 slidable in a bore 3 of the body 2 to permit flow of fluid from inlet 10 to outlet 11. The spool has a bore 19 in which is slidably received a spring-loaded piston 16, the end 21 thereof being subject through ports 20 in the spool to inlet pressure that under normal conditions neutralizes the spring-loading. The inlet pressure acts on an area equal to that of the piston cross-section on the spool while the outlet pressure passes through bores 23, 24 and restriction 18 of a secondary relief valve 25 to act on the whole of the area of the spool end in chamber 26. The spool thus acts as a differential piston reducing the pressure of the fluid passing through the valve. If the inlet pressure drops the spring-loading 30 of the piston 16 compensates to prevent outlet pressure drop. A main relief valve 37 is provided and is connected to a fluid return opening 12 as is a leakage passage 36 which is connected via bore 35 to waist 33 of piston 16.
